Just wondering how many people here use raid on their home desktop
I do as a rule. RAID1 on everything. With the cost of hard drive
storage as low as it is, it seems ridiculous to do otherwise. Most
corporate (Windows) PCs I purchase these days also come with RAID1
right out of the box.
In both of these cases, I'm talking about small drives (250-320GB for
home, as low as 80GB for corp) in the RAID1. They're only there for
the OS and application load. I keep my bulk media storage on a NAS
that has its own RAID5 or RAID10 configuration and is kept in a
closet. I like to keep my desktops small and simple, not a 4-drive
beast with a 600W power supply sitting under my desk.
Then, for those who do (or know how they would-do), what
partitioning do
you use -- a bunch (giving several mds), or one/few (possibly using
lvm
on top)?
I believe the mds should map closely to the physical drives, and LVM
should be responsible for the logical layout, so generally one huge md
with LVM sitting on top. The only exception to this might be a second
small md for /boot to simplify bootloader configuration. Also
remember that swap needs to either be inside the LVM or on its own
RAID set.
Or maybe there's some neat stuff by dropping the ext3/lvm blinders?
I always like to leave myself some room. I'll set up the volume group
to take everything available, but then I'll configure the initial
logical volumes to only add up to 50-80% of the available space. That
leaves me a pool for future expansion that I can use when a need
arises. Much easier on the brain than trying to guess how you'll be
using partition space a year from now.
